Half Capacity? No Problem!

Usually, standing on the median between the northbound/southbound lanes of Cootes Drive would be an unnerving experience, due to the high speed traffic clocking in at 80km/hour and more.

But during construction, the closure of the southbound lane of Cootes Drive (see video) has calmed traffic speeds and made the road quieter and safer.

With Spencer Creek and ponds to the left of the road, and Cootes Paradise Nature Sanctuary wetlands to the right, the inhabitants of the natural environment fare poorly when forced to interact with traffic. The huge distance between the shoulders of the road are a major barrier for amphibian and other wetland species, including species at risk like Cootes Paradise's turtle population.

When the road was built in 1936-37, it was built as an example of the new modern highway design: divided lanes with a grassy median, easy curves and low grades. These innovations were achieved in this instance by removing hills and then using the soil to fill in the marshy low ground, creating a dead-zone for wildlife. We have been paying the environmental cost ever since.

At Restore Cootes we advocate for the eventual removal of the road (replaced with an electric rail service), and the over-built capacity of the roadway suggests that reducing the lanes from 4 to 2, is not only possible, but in terms of traffic safety, desirable to control speeds. This would be a step in the right direction.

King Street West, over Hwy 403, half capacity,
no problem!

It is interesting that this kind of "experiment by necessity" is consistently undertaken during road construction projects around the city, and invariably traffic adapts to the changes so that there are no serious delays, or in most cases, any delay at all. Bridge work for the last two years on the prime arterial roads of King and Main over highway 403 provide another recent long-term example of lane capacity being cut in half, with no resultant traffic problems.

So, why do we pay for road maintenance and paving we don't actually require? With the traffic department spending on roads consuming over half the city's discretionary funds ($48.5 million of $93 million) and with a total annual budget of $75 million, roads are diverting money from other programs (recreation is the next closest category in discretionary spending at $6.1 million). City staff suggest they need to spend $140 million a year on road and bridge repairs alone (figures used from CATCH here).

Despite the huge costs, suggesting that we downsize our overbuilt roads is anathema to politicians and city staff. Yet the evidence we find in situ suggests it is not only possible, it happens all the time with no problem.

Guest Blogger: Carly Stephens Since its inception, Parking to Paradise has been a platform for interdisciplinary collaboration. Many readers are familiar with the Ancaster Creek riparian buffer and restoration work along the Northwest border of the parking lot. Interested parties across many faculties and disciplines have worked together to restore this ecosystem and raise awareness about the impacts urbanization on the natural environment. Nurtured by the time, commitment and hard work donated by volunteers and students, the land has grown into a site of green infrastructure, ecosystem restoration, and sustainable development. Read about Reyna Matties' Master’s work on retrofitting storm water management systems on the lot in the December 7, 2015 post below. Now, it’s the social sciences turn to learn where green infrastructure developments - as with the case of Lot M - fits into our social world.

Urbanization displaces and degrades ecosystems that are critical for humans, animals, and plants. Sustainable urban development has become a priority in the challenge to re-design our ageing infrastructure. Working to coexist peacefully with the surrounding environment will increase sustainability. As a graduate student of Biology at McMaster University, I am studying the applied ecology and hydrology of a parking lot system (Lot M). Ancaster Creek, a rare cold-water ecosystem, runs along Lot M and is part of an essential wildlife corridor for native species such as salmon, turtle, and deer. Together with Dr. Susan Dudley, I am working to retrofit the stormwater management of the system to minimize the impact of contaminants and runoff into the creek.

One method of achieving this goal is through increasing and restoring the land next to the creek. This is called a riparian buffer, which protects the system by providing habitat for animals, increasing sto…
